The hacker community is great at making brilliant tools and solving fascinating problems, but we often suck at making the tools and solutions available to the rest of humanity - sometimes even to ourselves. UX and usability are frequently dismissed or misunderstood as the superficial art of adding unnecessary whitespace to perfectly usable things. The assumption is that the prospective users should just "get better" at using computers. That's all quite bad - but what's even worse, we often forget that the user - their human brain and their human perception - is often the biggest attack surface, and as we harden our solutions against all technical threats, we prefer to ignore this one.
